PAUL F. WILLIAMS, OF CHICAGO?, ILLIN'GIS, ASSIGNQR T@ G du V7 ELECTRIC SPECIALTY 00.., 0F CHICAGO, ILLINOIS, A CRPQRATIQN 0F ILLINOIS.

PQTI-IEAD,

vBe it known that I, PAUL F. Vntrimrrs, citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a certain new and useful Improvement in Iotheads, of which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to terminals for electric cables or conductors, commonly called pot heads. The principal object is to provide a simple, practical and e'ective device of this kind for terminating a cable, having a plurality of members, strands or conductors, and arranging for the leading out of the different members, strands or conductors separately or individually. To such end, I provide a structure, having a casi-ng with an opening at one end to receive a single cable, or several cables hunched or grouped together, and at the other end with a plurality of outlets for the several cables, strands or conductors to be taken out separately. The casing is preferably provided with removable members, by which access can be gained to its interior, and the individual outlets are also desirably provided with removable parts or sections for convenience of access to their interior.

In the accompanying drawings, Figure 1 is a perspective view of a pot head, embodying my present invention. Fig. 2 is a vertical section of the same. Fig. 3 is a vertical section of one of the outlets of the device. Figs. 4 and 5 are cross-sectional views of the same, taken on lines 4 4 and 5 5 in Fig. 3. Fig. 6 is a vertical section of a modification, and Fig. 7 is a cross-section taken on line 7 7 in Fig. 6.

Referring first to the device shown in Figs. 1 to 4inclusive, I show a casing 1, which may be made of insulating material, or metal, as desired, having a converging jbottom, 2, provided with a tubular portion 3, serving as an inlet for a cable 4. A. lid

` or conductors of the cable, or for different 5 is fitted upon the upper open end of the casing l. This lid is bodily removable from the casing, and is provided with a plurality of outlets for the different members, strands cables. In the drawings, I have shown three such outlets, 6, although, of course,

the number could be varied. These outlets 6, 6 are secured firmly to the lid 5, as for example, by making them integral therewith, and are provided with removable caps 7, 7, lf/'ithin the outlets are connecting devices conveniently consisting of cable terminals 8, 8 and conductor terminals 9, 9, whereof each terminal 8 consists of a plug shaped device, `having a socket at each end, the upper one for the terminal 9 and the lower one for the end of the cable 12. A

fiat member or web 10 is tted upon the terminal 8, the web having an aperture, through which the terminal can pass. The terminal 8 is provided with a couple of lugs, 8a, 8e, and the web 10 with a couple of corresponding apertures, whereby the terminals can be passed up from below, and then the web turned to lock the terminal in position, it being' noted that the lower portion of the bore of the outlet 6 is slightly contracted to form a ledge, on which the web 10 rests. The terminal 9 has a plug member 11, adapted to enter the socket at the upper end of the member 8, and is also provided with a member 13, for engaging the conductor which is led out from the device.

The lower members 8, 8 are intended to lit removably in the outlet tubes 6, 6, whereas the upper members 9, 9 fit upon the removable caps 7, 7. The general form of of any suitable or desired kind, preferably an insulating compound. Thus the cable with its three strands, or conductors, or parts, is led into the casing 1, and then its members are separated and connected With the cable ends of. the connecting devices, and then the cover is'put on and the removable webs are put in and given quarter turns to lock the connecting devices in place.

The insulating compound is filled into the casing before the lid 1s put on, and into the outlets after the Webs are put in and locked, before` which, however, the bottoms of the tubes are closed by plugs of tape 6a. Then the caps 7 7 are placed in position. Connection is thus made with the different parts or members of the cable, and if at any time 'Q neas it is desired to disconnect the same, the caps or any oi3 them are removed. These caps can loe removed and replaced as desired, to make any connection or disconnection.

ln the device shown in Figs. 6 and 7, L provide a casing l, having a contracted opening 43, for a cable, and having lid or cover 5, the same as the device previously described. The outlet tubes 5, 6, however,

do not contain the connecting devices shown in the said other construction, but instead of that the several cable members are run directly through the outlets, and caps, as shown in Fig. 5, the latter having straight bores of uniform diameter, as shown in said figure. lnsulating material is filled into the casing and outlet tubes, the same as in the other construction.

lt Will be understood that changes and modifications can be made Without departing from the spirit of the invention.
